       pvscan - scan all disks for physical volumes

SYNOPSIS

       pvscan [-d|--debug] [-e|--exported] [-h|--help] [-n|--novolumegroup] [-s|--short] [-u|--uuid] [-v[v]|--verbose [--verbose]]

DESCRIPTION

       pvscan scans all supported LVM block devices in the system for physical volumes.

   OPTIONS
       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -e, --exported
	      Only show physical volumes belonging to exported volume groups.

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -n, --novolumegroup
	      Only show physical volumes not belonging to any volume group.

       -s, --short
	      Short listing format.

       -u, --uuid
	      Show UUIDs (Unifrom Unique Identifiers) in addition to device special names.

       -v, --verbose
	      Gives  verbose  runtime  information about pvscan's activities.  If given a second time it displays the attributes of found physical
	      volumes like pvdisplay(8) does.

DIAGNOSTICS

       pvscan returns an exit code of 0 for success or >0 for error:

       2  no physical volumes found
